Scientifically, this magical "gas" is known as Fast-Anodizing Regressive Thorium, but its cloudy appearance has earned it the nickname "mist". Collecting this gaseous substance and releasing it in concentrated blasts while in the Burroughs Rift attracts more powerful (and profitable!) mice.

But be warned! Releasing too much of this mist increases the concentration of airborne Thorium to hazardous levels, bringing about some very tough mice who are attracted to the biohazardous scent.
